Alzheimer's Disease Acitretin Medication (ADAM)

Changes of Cerebral Spinal Fluid APPSα Levels Under Oral Therapy With Acitretin 30 mg Daily in Patients With Mild to Moderate Alzheimer's Disease: a Multicenter Prospective Randomised Placebo-controlled Parallel-group Study

The trials investigates the changes of cerebral spinal fluid (CSF) soluble alpha-secretase cleaved APP (APPsα) levels under oral therapy with acitretin 30mg daily in patients with mild to moderate Alzheimer's disease (AD).The present study aims to demonstrate an enhancement of the α-secretase activity by acitretin as measured by increased CSF APPSα levels in human AD. Second, the safety and tolerability of acitretin in AD patients should be proven.
